We hooked up my car battery to another car with the jumper cables. As he accelerated, i tried to turn the key and the car still wouldn't start
Hello. This suggests you have a faulty connection or a power shortage somewhere in your electrical system if there is no power coming to your car from the other car. If there is power, but just a clicking sound this may be a faulty starter relay. I recommend having a certified professional from YourMechanic come to your car’s location to inspect the starting issue and follow through on the appropriate new repairs.
